Is anyone on here familiar with Extreme Toolboxes? I am looking at a 55" top and botom combo from them. The part numbers that I am looking at are EX5511RC and EX5510CH. How are they built compared to Snap On, Mac or Matco? The Extreme is more in my price range. I have a Craftsman 1470 pc tool set. I would like to have one of the bigger name brands but I can't afford to put 7 or 8 grand in a box right now. Thanks in advance. Jethro
